Microbial communities living in deep aquatic sediments have adapted to survive on degraded organic matter, according to a study published in Applied and Environmental Microbiology and coauthored by professors at the University of Tennessee, Knoxville.

Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study by the University of Cincinnati.

Hand-raising monarch butterflies in the midst of a global extinction crisis, Laura Moore and her neighbors gather round in her suburban Maryland yard to launch a butterfly newly emerged from its chrysalis. Eager to play his part, 3-year-old Thomas Powell flaps his arms and exclaims, "I'm flying! I'm flying!"

A new study in The Condor: Ornithological Applications finds that currently-available global positioning system (GPS) tracking devices, previously thought to not alter animal survival rates, can decrease greater sage-grouse survival.

About 35 million years ago, an asteroid hit the ocean off the East Coast of North America. Its impact formed a 25-mile diameter crater that now lies buried beneath the Chesapeake Bay, an estuary in Virginia and Maryland. From this impact, the nearby area experienced fires, earthquakes, falling molten glass droplets, an air blast and a devastating tsunami.

A coalition of 22 US states and seven cities on Tuesday sued President Donald Trump's administration to block it from easing restrictions on coal-burning power plants.

Scientists have discovered how diatoms—a type of alga that produce 20 percent of the Earth's oxygen—harness solar energy for photosynthesis.

A low-cost intervention aimed at fostering a growth mindset in students gave the students more confidence in their entrepreneurship abilities and helped them persist when challenges arose.

Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell University research.

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study by Masayuki Shimada and colleagues at Hiroshima University, published on August 13 in the open-access journal PLOS Biology. The study was performed in mice, but the technique is likely to be widely...

Wildfires in the Arctic often burn far away from populated areas, but their impacts are felt around the globe. From field and laboratory work to airborne campaigns and satellites, NASA is studying why boreal forests and tundra fires have become more frequent and powerful and what that means for climate forecasting, ecosystems and human health.

Unlike people, crocodiles do not clean their teeth to slow down wear and tear. Instead, they get rid of them and replace them with new copies.

A molecule called tRNA, or transfer ribonucleic acid, is an essential component of the human genome that acts as a translator. It reads the genetic code and translates it into proteins—one of the key building blocks of the human body.

Researchers at the University of South Florida are harnessing the power of human physiology to transform greenhouse gases into usable chemical compounds—a method that could help lessen industrial dependence on petroleum and reduce our carbon footprint.

The first Americans—humans who crossed onto the North American continent and then dispersed throughout Central and South America—all share common ancestry. But as they settled different areas, the populations diverged and became distinct. A new study from North Carolina State University shows that facial differences resulting from this divergence were due to the complex interaction of...

Climate change is a problem facing countries around the world, but media coverage of the topic differs from one nation to the next. A new study from the University of Kansas shows the way media frame climate change coverage can be predicted by several national factors, yet none tend to frame it as an immediate problem requiring national policies to address the issue.

Infrared imagery from NASA's Terra satellite found just a few scattered areas of cold clouds in the Eastern Pacific Ocean's Tropical Depression Henriette on August 13.

Scientists at the National University of Science and Technology "MISIS" (NUST MISIS) have identified a new mechanism for removing magnetic nanoparticles through the kidneys, which will help to create more effective and safe drugs. The results of the study are published in the Journal of Controlled Release.

Countries should be strengthening their laws protecting endangered species, not weakening them, international conservationists said Tuesday, after US President Donald Trump's administration announced plans to alter the country's Endangered Species Act.

A year after starting a school strike that made her a figurehead for the fight against global warming, Greta Thunberg believes her uncompromising message is getting through—even if action remains thin on the ground.

Researchers from the University of Pittsburgh, UCLA and the University of Texas published new research in the INFORMS journal Marketing Science (Editor's note: The source of this research is INFORMS), that reveals the power of word-of-mouth in social learning, even when compared to the power of following the example of someone we trust or admire. The same research found, however, that both...

NASA's Aqua satellite passed over the Northwestern Pacific Ocean and captured a good shot of the wide, ragged center of circulation in Tropical Storm Krosa.

To understand the most ordinary matter in the universe—and the extraordinary things that happen to it—a Yale-led team of astronomers took a deep dive into the cosmic fog.

Researchers from the University of Kansas have described three genera and 17 new species of water scavenger beetles from the Guiana and Brazilian Shield regions of South America, areas seen as treasure houses of biodiversity. The beetles from the countries of French Guiana, Suriname, Brazil, Guyana and Venezuela were discovered through fieldwork and by combing through entomological collections at...
